Stator for an electrical refrigerant drive and electrical refrigerant drive for a motor vehicle

Abstract

A stator for an electrical refrigerant drive includes a laminated core wound with a stator winding, and a contact adapter mounted on the laminated core for connecting the stator winding to at least one phase connector. The contact adapter has at least one potting pocket and the phase connector is fitted in the potting pocket. A winding portion of the stator winding is guided into the potting pocket and contacted with the phase connector. The potting pocket is filled with a cured potting material. A motor vehicle electrical refrigerant drive having the stator is also provided.

The invention claimed is: 
     
         1 . A stator for an electrical refrigerant drive, the stator comprising:
 a stator core being wound with a stator winding having a winding portion;   at least one phase connector having a phase pin, a conductor path contacting said phase pin and being configured for contacting said winding portion, and a phase dome;   a contact adapter attached to said stator core for connecting said stator winding to said at least one phase connector;   said contact adapter having at least one potting pocket, said at least one potting pocket having integrally molded positioning elements for positioning and mounting the phase connector;   said at least one phase connector being inserted into said at least one potting pocket;   said winding portion of said stator winding being guided into said at least one potting pocket and contacting said at least one phase connector; and   a cured potting material filling said at least one potting pocket;   said phase dome having mating contours for said positioning elements of said at least one potting pocket.   
     
     
         2 . The stator according to  claim 1 , wherein said at least one potting pocket is formed by a projecting periphery being closed in an encircling manner and integrally molded on said contact adapter. 
     
     
         3 . The stator according to  claim 1 , wherein said at least one potting pocket has an integrally molded guide contour for guiding said winding portion. 
     
     
         4 . The stator according to  claim 3 , wherein said integrally molded guide contour of said at least one potting pocket is at least one of a wire-guiding groove or a wire-guiding ramp. 
     
     
         5 . The stator according to  claim 1 , wherein said conductor path has a U-shaped contact region for contacting said winding portion. 
     
     
         6 . The stator according to  claim 1 , wherein said phase dome is embodied as an overmolding of said phase pin and said conductor path. 
     
     
         7 . An electrical refrigerant drive for a motor vehicle, the electrical refrigerant drive comprising a stator according to  claim 1 .
